Question

multiple choice question complex ringed compounds commonly found in cell membranes and as animal hormones belong to the lipid group called steroids lipoproteins triglycerides phospholipids need help? review these concept resources.

Explanation:

Steroids are complex - ringed compounds. They are found in cell membranes (cholesterol is a steroid component of cell membranes) and some are animal hormones (such as testosterone and estrogen). Lipoproteins are complexes of lipids and proteins, not a lipid group. Triglycerides are composed of glycerol and fatty - acids and do not have complex ring structures like steroids. Phospholipids have a phosphate group and are important for cell membranes but do not match the description of complex - ringed compounds as animal hormones.

Answer:

steroids
